This comics comes timely as I attempted to figure out how to make Audible.com work on Linux this weekend, and gave up.  I don’t get why vendors don’t switch from DRM to watermarking (like a lot of people doing eBooks now).  Watermarking makes your customers part of your enforcement, as their name gets badly spread around if their files get out in bittorrents, and it doesn’t prevent your customers from using their purchased items in all the legitimate ways they want.
